IMPORTANT NOTES

SignaLink USB Users - The
SignaLink USB is always powered by the computer's USB jack. When
installing the jumpers for the SignaLink USB using the settings shown here
and in our other documentation, please disregard the PWR jumper (do
NOT install it!). All other jumper settings are the same. Note that if you
mistakenly install the PWR jumper, it will make no difference in the
operation of the unit as this pin is not internally connected.

Select The Correct Diagram - When
viewing the jumper settings below, BE CERTAIN THAT
YOU ARE LOOKING AT THE CORRECT DIAGRAM for the radio connector
that you will be using. For any given radio, there are likely to be a
different jumper settings for the Mic, Data and Accessory Port connectors.

Jumper Wire Color - The
jumper wires in the diagrams below are shown in color for illustrative
purposes only. The color of the wires means nothing - they're just
easier to see! The actual jumper wires that are included with the
SignaLink are all the same color and can be used to jumper any signal.

RJ-45 Mic Connectors - There is a lack of
standardization in the way that radio manufacturers number their RJ-45 Mic
connectors. We have numbered our connector according to the dominant
industry standard (as shown below), and all jumper settings shown in our
documentation reflect this standard. Icom and Radio Shack follow
this standard, but Kenwood, Yaesu and some others do not. All of
the jumper settings show below have been corrected as necessary to account
for any reversed pin numbering. If your
radio is not shown below and you need to figure out your own jumper
settings, then you will need to carefully determine how your mic connector is
numbered to avoid reversing the connections!

Standard
Kenwood, Yaesu, Some Others

PTT - You should verify in your radio manual that the
radio PTT requirements do not exceed the specifications of the SignaLink
keying circuit (please refer to the SignaLink manual) and that the PTT line is Grounded to make the radio
transmit. If your radio exceeds the specifications listed or requires some other
keying arrangement, then please contact our Technical Support Staff for
suggestions.

POWER - The SignaLink
SL-1 and SL-1+ can usually be powered by the Accessory Voltage found on the Mic and Accessory Port
connectors of most radios. If power is not shown in the jumper
settings for your radio, then consult your radio manual to see if it is
available. The SignaLink SL-1 and SL-1+ requires 6.75 to 15 VDC at 13ma
(nominal). If this power is not available from your radio, then you will need to power the SignaLink
SL-1 or SL-1+ externally (see the SignaLink manual for details).Note
that the SignaLink USB is always powered by the computer, so you can
disregard the PWR jumper when installing this unit.

RECEIVE AUDIO / SPEAKER AUDIO
-

Receive
Audio is available on the Mic, Data, and Accessory Port connectors of most
radios. If Receive Audio is not shown in the jumper settings for your
radio, then consult your radio manual to see if it is available. If it
is not, then you will need to connect an audio cable between your radio's
External Speaker or headphone jack, and the "Speaker" jack on the
back of the SignaLink. See the SignaLink Installation Manual for
details.

NOTE: Please
read the "Important Notes" above BEFORE you select your jumper
settings. This will save time and may help prevent you from making a
mistake that could possibly damage the SignaLink or your radio. Note that
the SignaLink USB does NOT use the PWR jumper wire, so you can disregard this
jumper during installation. All other jumper settings are the same.

NotesSome customers have found that the K3's "Line In" gain
(menu setting) is set to zero by default, thereby resulting in no power
output when transmitting. If up experience this problem, then please
consult your radio manual for instructions on turning up this control.

Note that the K3 also has a menu setting for the "Line Out"
level, which can be turned up if needed to increase the RX Audio going
into the SignaLink.

NotesTwo cable connections are required from the
SignaLink to the Elecraft KX2/KX3 as follows:

Connect the RJ-45 end of the SLCABKX3 radio cable to the SignaLinks
Radio connector. Connect the 4-pin right-angle TRRS plug
to the KX2/KX3s Mic jack, being sure to fully insert the plug.

Connect the supplied right-angle mono audio cable between the
SignaLinks SPKR jack, and the KX2/KX3s Phones jack. Be
sure that both plugs are fully inserted.

KX2/KX3 Radio Settings:

1 - The Mic Bias setting in the KX2/KX3s menu system should be
turned OFF if you are using jumper wires. This setting can be left ON if
you are using our SLMODKX3 jumper module as it has a built-in DC blocking
capacitor.

2 - The Mic Btn setting should be set to either PTT, or PTT
Up.Dn..

NotesFor special signals requiring un-filtered
"discriminator" audio, you will need to move the "SPKR"
jumper to pin #4 (9600 baud output). Note that some newer radios do
NOT provide this output, so this may not apply to your radio.

Power is not available on any 6-pin mini DIN Data Port, so
you will need to use external power for the SignaLink Model SL-1+.

The SignaLink USB is always powered by the
computer and never needs external power.

**IC-703 - If you are using the Data Port on
this radio, then you must set menu #36 to "1200".

**IC-706MKIIG - If you are using the Data Port on
this radio, then you must set menu #29 to "1200".

**IC-746PRO / IC-7000 - Some users have reported that this
radio has a very sensitive Data Port, making power adjustments with the
SignaLink USB's TX knob somewhat touchy. If this is the case with
your radio, then please click here
for a simple solution to this problem.

**Mic audio is NOT muted on this radio.

##You will need to connect the SignaLink to the
"Main" data port connection on this radio (not the
"Sub" port).

**Some customers have reported that
the IC-746 (early model only) does NOT mute the Mic when keyed from the
Accy Port. If this is the case with your radio, then you will need
to turn the radio's Mic Gain down and/or unplug the microphone.

**Due to the design of the IC-746PRO, this jack
does NOT support VHF operation. If you want to operate both HF and
VHF, then you'll need to use the 6-pin mini-DIN Data Port instead.

NotesFor VHF operation on the IC-706 and
IC-706MKII you will need to move the PTT
jumper to Pin #4.

For VHF/UHF operation on the IC-706MKIIG and
IC-7000, you should turn the following "VSEND" menu item to OFF:

Item #30 for IC-706MKIIG

Item #20 for IC-7000

This will force the radio to use the same PTT pin
for all bands so you will not need to change the SignaLink's jumper settings.

**The IC-718 does NOT mute the Mic jack when
using the 13-pin Accy Port, so you will need to turn the Mic Gain down.

**The IC-7000 does NOT mute the Mic jack when
using the 13-pin Accy Port, so you will need to turn the Mic Gain down, or use
the 6-pin Mini Din Data Port instead.

**Some customers have reported that the new
IC-7100 doesn't mute the microphone jack, so you will need to turn the Mic Gain down, or use
the 6-pin Mini Din Data Port instead.

24-pin DIN Accessory Port Connector - Tigertronics does
not manufacture a cable for the ICOM 24-pin Accessory Port connector, but you
can easily build one using our un-terminated radio cable (p/n SLCABNC). To
build your cable, simply wire it straight-through for pin numbers 1-8 (Pin #1 to Pin #1,
Pin #2 to Pin #2, etc.). Note that your cable MUST wired straight-through
or the jumper settings shown below will NOT work, and you might DAMAGE YOUR RADIO OR THE SIGNALINK!

NotesPins marked as "NC" are not used by the SignaLink, but
might be connected internally inside the radio.

NotesFor special signals requiring un-filtered
"discriminator" audio, you will need to move the "SPKR"
jumper to pin #4 (9600 baud output). Note that some newer radios do
NOT provide this output, so this may not apply to your radio.

Power is not available on any 6-pin mini DIN Data Port, so
you will need to use external power for the SignaLink Model SL-1+.

The SignaLink USB is always powered by the
computer and never needs external power.

**Only European models of the TM-271 and TM-271A
have the 6-pin mini-DIN Data Port. All other models will need to use
the RJ-45 Mic cable.

13-pin DIN Accessory Port Connector (use
SLUSB13K, SL1+13PK or SLCAB13K) Our 13-pin cable
works with ALL Kenwood radio's that have a 13-pin Accessory Port,
however there are two
possible jumper settings. If your radio is not listed in Figure 1 or Figure 2, then you will
need to try both jumper settings to determine which PTT configuration your radio
requires. We suggest that you try the settings in Figure 1 first. Your
radio will NOT be damaged if you install the PTT jumper using the wrong
configuration - you just wont be able to transmit! After you
have installed the jumpers, be sure to set the sound card audio levels as
outlined in the SignaLink manual. If you do not set the levels correctly, then
the SignaLink may not transmit, and you might mistake the problem for incorrect
jumper settings. Note that external power is required for the SignaLink
Model SL-1+.

Notes

This configuration is the most common and works with early Kenwood radios such as the TS-140,
TS-450S, TS-680, TS-850, TS-870 and TS-950. Some newer radios such as the
TS-570D, TS-590S, TS-990 and TS-2000/X also use these settings.

This configuration is less common and is used by some newer radios
(TS-690 for example) and some older radios such as the TS-440. These settings are identical to those in Figure 1, except
for the PTT jumper, which has been replaced by a diode module (supplied
with cable).

TS-2000 users should set menu item 50E to
Main, and 50F to 1200
Baud. Menu 50B can be used to increase the radio's power output if
it is too low, and menu 50C can be used to adjust the Receive Audio
level.. We suggest that you change these menu items even if they
already appear to be set correctly (set 50F to 9600,
and then back to 1200, etc.).

TS-570 users should set Menu #33 to 1 or 2
(a setting of zero will result in no transmit power). Menu #34
should be set at 4-5 and can be increased to provide more Receive Audio if
needed.

TS-940 users need to use the jumper
settings shown in figure 1, except for the PTT jumper. The PTT
jumper should be connected to pin #4 instead of pin #3.

TS-440 users please note that your radio's
Mic Gain control will affect your power output. We suggest setting
this control to 50% and then adjust it as needed so that the SignaLink's
TX knob can be used to adjust the power output properly.

NotesPower is not available on this connector, so
you will need to use external power for the SignaLink Model SL-1+.

The SignaLink USB is always powered by the
computer and never needs external power.

**On the FT-920, the AFSK/FSK switch MUST be set
to AFSK, and you must be in "Data" mode (push the front panel
"Data" button). The Mic Gain control appears to affect the
operation of the Packet jack, so we suggest setting this to 50% and then
adjusting as needed..

**The FT-1000MPMKV and FT-1000MKV Field MUST be in "Packet" mode (NOT
usb!) for digital operation. For PSK31 or other "USB"
digital modes, you'll need to set your radio's "User Mode" (selection
8-6) to "PS31U". This will configure the radio to look at the Packet jack and use the correct side band for PSK31. For more detailed information on this (including settings for other modes), see "Digital Modem Operation" in your radio manual.

**The 5-pin DIN jack on this radio supports only FM and LSB, which
are not compatible with the majority of digital modes. We recommend
connecting the SignaLink to the Mic jack instead.

##Detailed setup information for this radio is now available thanks to
Wade Bolling, W5ERX. Please click
here for details.

NotesFor special signals requiring un-filtered
"discriminator" audio, you will need to move the "SPKR"
jumper to pin #4 (9600 baud output). Note that some newer radios do
NOT provide this output, so this may not apply to your radio.

**FT-450 - Some users have reported that this
radio has a very sensitive Data Port, making power adjustments with the
SignaLink USB's TX knob somewhat touchy. If this is the case with
your radio, then please click here
for a simple solution to this problem.

**FT-950 - Some users of this radio have reported
that the Notch Filter is turned on after a hard reset. If you see a
"hole" in your waterfall display, then please make sure that
your Notch Filter is turned OFF.

**The 6-pin mini-DIN Data Port on the FT-840 and FT-847 supports
FM and LSB only making it incompatible with most digital modes. On
the FT-847, this jack also appears to function only on the VHF/UHF bands.
Unless you are running digital modes that use LSB or FM you will need to
connect the SignaLink to the Mic jack, or in the case of the FT-847, the Data I/O
jack (see below).

**The FTM-350 requires Yaesu's CT-141 adapter to
convert from it's 8-pin mini-DIN connector to a standard 6-pin
mini-DIN. This adapter should be available from any authorized Yaesu
dealer.

##The FTM-100DR and FTM-400 requires Yaesu's CT-164 adapter to
convert from it's 10-pin mini-DIN connector to a standard 6-pin
mini-DIN. This adapter should be available from any authorized Yaesu
dealer.

NOTE: We now offer a
fully assembled radio cable and jumper module for this connection. Order
radio cable p/n SLCAB847 and jumper module p/n SLMODHT.

For HF Only operation on the FT-847, we recommend that you
attach the SignaLink to the "Data I/O" jack. This jack works
for virtually all sound card digital and voice modes, and will let you keep your microphone plugged into the
radio.

The values shown below for R1 and C1
have been used for years in a number of our products.
You can use these values, or those shown in the FT-847 manual. Both will
work just fine.
